12oz Double Wall Vacuum Insulated Stainless Steel Tumbler with Handle

What are the exact dimensions and weight of the 12oz Double Wall Vacuum Insulated Wide Mouth Tumbler?

The tumbler holds 12 ounces (355 ml) and stands approximately 5.5 inches tall with a base diameter of about 3.2 inches. It weighs around 0.45 pounds (200 grams). These dimensions make it compact enough to fit most standard car cup holders and easy to carry by the handle.

How long does the double-wall vacuum insulation keep drinks hot or cold?

When pre-conditioned (preheated with hot water or pre-chilled with ice water for a few minutes), the insulation keeps hot drinks hot for up to 6 hours and cold drinks cold for up to 12 hours. The wide mouth also allows you to add ice cubes for extended cold retention.

Is the lid leak-proof, and can I use the tumbler for carbonated beverages?

The lid is designed to be leak-proof when properly closed, making it suitable for travel and outdoor use. However, we do not recommend using it for carbonated beverages because pressure buildup can cause the lid to leak or pop open. It is best used for still drinks like water, coffee, tea, or juice.

What materials is the tumbler made of, and is it BPA-free?

The tumbler is made from high-quality 18/8 stainless steel (inner and outer walls) that is food-grade, rust-resistant, and completely BPA-free. The lid is constructed from durable, food-safe polypropylene (PP #5) plastic with a silicone gasket. All materials meet FDA standards for safe beverage use.

Can I put this tumbler in the dishwasher or microwave?

The stainless steel body is dishwasher safe, but we recommend hand washing the lid to preserve the silicone seal and prevent warping. The tumbler is not microwave safe because stainless steel can damage the microwave and cause sparks. For cleaning, use warm soapy water and a bottle brush, thanks to the wide mouth design.

Does this 12oz tumbler fit in standard car cup holders?

Yes, with a base diameter of approximately 3.2 inches (8.1 cm), it fits most standard cup holders found in cars, trucks, and SUVs. The tapered shape and integrated handle allow for easy insertion and removal without getting stuck.

What is the warranty and return policy for this tumbler?

The tumbler comes with a 1-year limited warranty against manufacturing defects in materials and workmanship. If you experience issues such as insulation failure or lid defects within the first year, we will replace or refund the product. Returns are accepted within 30 days of purchase as long as the item is unused and in original packaging.

Is customization, such as engraving or additional color options, available?

Currently, we offer the tumbler in standard colors (black, white, silver, and navy) but do not support individual engraving or custom logos through this listing. However, the smooth stainless steel surface is suitable for aftermarket customization by third-party services.

Usage Instructions

• For best thermal performance, preheat the cup with hot water (for hot drinks) or pre-chill with ice water (for cold drinks) for 2-3 minutes before filling.
• After filling, close the lid securely to prevent leaks.
• The cup is suitable for still beverages such as water, coffee, tea, and juice.

Precautions

• Do not use the cup for carbonated beverages, as pressure may cause the lid to leak or pop open.
• Do not microwave the cup; stainless steel can damage the microwave and cause sparks.
• The stainless steel body is dishwasher safe, but hand washing the lid is recommended to preserve the silicone seal and prevent warping.
• Avoid using abrasive cleaners or scouring pads on the exterior powder coating to maintain finish.
• Keep the cup away from direct heat sources (e.g., stovetop, oven).
